Kindergarten children's estimates of numerosity
… kindergarten children's ability to estimate the numerosity of sets of up to 40 objects on different types of estimation tasks. The contributions of specific mathematics skills hypothesized to be prerequisites for estimation were also investigated. Kindergarten children were highly successful with …

The Representation Of Numerosity In The Human Brain And Machines
The capacity to estimate the number of objects (numerosity) in the environment is ontogenetically precocious and phylogenetically ancient. In animals, this ability holds significant adaptive advantages, directly influencing survival and reproductive success. In humans, it may serve an additional …

Nonstandard Models in Measure Theory and in functional Analysis
… with a suitable unit of measurement, from a numerosity it can be defined a non-atomic real-valued measure, and that every non-atomic measure can be obtained from a numerosity by this procedure. We then used numerosities to develop a model for the probability of infinite sequences of coin …

An action research investigation into the effectiveness of number testing of a group of young adults with learning difficulties in a further education setting
… the need for more targeted tests for subitising, numerosity and ordinality.

How many can you see at a glance? The role of attention in visual enumeration
… controversy as to how the brain extracts numerosity information from a visual scene and as to how much attention is needed for this process. Traditionally, it has been assumed that visual enumeration is subserved by two functionally distinct mechanisms: the fast and accurate apprehension …

Clinical Studies of Counting Problems With Primary School Children
… a process and often has little relationship to numerosity. Children's process schemas were separate from quantity schemas. Each of them operated at different times to solve counting problems. Children counted but didn't find the answer to ""How many?"""

The face is the thing: faces as a whole are responsible for the lateralization of visual perceptual facial processing
… tasks are judgments of facial features, emotion, numerosity, facial resemblance, gender, and line midpoint. Verbal tasks typically display a left hemisphere bias whereas spatial tasks typically display a right hemisphere bias. In an initial study using factor analysis to examine the relationship …

An Assessment of Number Representation in the Small-Eared Bushbaby (<i>Otolemur garnettii</i>)
… or what system is employed. Furthermore, primate numerosity research has been almost exclusively conducted within haplorhine species (monkeys and apes). Within the strepsirhines (lemurs, lorises, and galagos), it has only been investigated in 15 diurnal and cathermal Malagasy primate species. No …

The association of working memory and anxiety with skill acquisition and transfer in young and older adults
… arithmetic task in Experiment I, and a visual numerosity task in Experiment 2. In each experiment, participants received 240 trials of the task during u training phase (in which one set of stimuli were used) and 240 trials during a transfer phase (in which a second set of stimuli were used). …

The Effect of Aging on Object Representation
… experiments addressing the impact of object numerosity and/or nature in OAs’ attention deployment during a visual search task. Results of two experiments in Chapter 4 with manual responses found that OAs’ performance was detrimentally impacted by the amount of object representations, …

Processing of quantitative information, investigated with fMRI.
… limit is not present (or less stringent) when numerosity is not behaviourally relevant. This could explain the finding of number-sensitive neurons for larger numerosities in monkeys. Finally, we suggest that a different mechanism is employed when numerical value of large numerosities is …

Subitizing Activity: Item Orientation with Regard to Number Abstraction
Subitizing, a quick apprehension of the numerosity of a small set of items, is inconsistently utilized by preschool educators to support early number understandings (Sarama & Clements, 2009). The purpose of this qualitative study is to investigate the relationship between children’s number …

The development of number processing and its relation to other parietal functions in early childhood
… phenomenon could be due to the refinement of the numerosity acuity during the acquisition of symbolic knowledge for numbers. Among the tested parietal functions, we observe a strong association between the numerical and the finger domain, especially in children. In preschoolers, finger gnosis is …

Transfer of automatic skills: the role of automaticity in skill acquisition and transfer
… based on Lassaline and Logan’s (1993) visual numerosity task and Speelman and Parkinson’s (2012) two-step task design. The study has a particular emphasis on individual differences, and thus individual participant data are explored to determine the pervasiveness of trends observed in the group …

Comparative Studies of Numerical Cognition in Nonhuman Primates: From Numerical Comparison to Arithmetic
<p>There is a long-standing claim that humans and nonhuman primates share an evolutionarily ancient system of nonverbal number representation. By and large, the focus in the field has been on providing existence proofs of numerical competence in wide-ranging taxa or using individual species as …

Modeling Cognition by Pruning and Topography-Learning in Deep Neural Networks
… units or by population-level geometry. Using numerosity as a controlled domain, we find that the units critical for capturing similarity judgments, identified via the same pruning method, do not overlap with the units identified via a traditional statistical test (ANOVA). This suggests that …
